[0002] Refer to the attached Figure 1 The figure shows the schematic diagram of the principle structure of the existing bladder fistula tube wound dressing. The fistula tube 1' is inserted into the patient's bladder, and the dressing layer 2' is adhered to the patient's bladder wound by the adhesive tape 3'. The dressing in the dressing layer 2' is squeezed and filled on the periphery of the fistula tube to prevent external bacteria from entering the patient's bladder wound. However, in the actual process, there is a gap between the dressing and the fistula tube, and since the fistula tube is easy to move up and down, external bacteria can easily enter and cause wound infection. Therefore, it is necessary to disinfect and change the dressing every day or every other day to keep the fistula opening and the surrounding skin dry and clean, and prevent the fistula opening from being infected, which leads to excessive nursing workload and high requirements on the nursing skills of the patient or family members; and due to repeated disinfection and dressing changes, the economic burden on the patient is relatively large. Summary of the invention

[0003] In view of the defects existing in the prior art, the purpose of the utility model is to provide a maintenance-free sealing protective patch for cystostomy tube fistula wound, so as to solve the problem of heavy nursing workload and heavy economic burden caused by frequent disinfection and dressing changes due to the gap between the cystostomy tube and the dressing.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] The present application provides a maintenance-free sealing protective patch for a bladder fistula tube and a fistula wound, the sealing protective patch comprising an elastic hose, a film and a dressing extrusion layer, the elastic hose comprising an elastic hose body, an open end formed at the top of the elastic hose body for inserting the fistula tube, and an annular folded end arranged at the bottom end of the elastic hose body, the outer surface of the annular folded end is formed with a plurality of annular folds extending outward, the film is horizontally formed at the outer edges around the bottom opening of the annular folded end, and the dressing extrusion layer is bonded to the bottom end of the film.

[0006] Furthermore, a blocking portion is formed on the inner wall of the open end of the elastic rubber tube to prevent the fistula tube from falling off.

[0007] Furthermore, the blocking portion is a plurality of annular valve protrusions formed on the inner wall of the open end of the elastic rubber tube, and the plurality of annular valve protrusions are arranged at intervals along the length direction of the elastic rubber tube.

[0008] Furthermore, the outer edge of the film extends to the periphery of the dressing extrusion layer.

[0009] Furthermore, the film includes a waterproof and breathable film body and an adhesive layer arranged at the bottom end of the waterproof and breathable film body.

[0010] Furthermore, the elastic hose body and the annular folded end are integrally formed.

[0011] The beneficial effects of the utility model are:

[0012] By adding an elastic hose and a film, the elastic hose is sleeved on the outer surface of the fistula tube, so that the inner wall of the open end at the upper end of the elastic hose can be tightly fitted on the outer surface of the fistula tube, and at the same time, the film is horizontally formed at the outer periphery of the opening of the annular folded end at the bottom end of the elastic hose. When in use, the film fits the skin around the patient's bladder wound, and the dressing is filled around the wound and the fistula tube. Therefore, the dressing is in a sealed space formed by the elastic hose, the film, the outer wall of the fistula tube and the bladder, and it is difficult for external bacteria to enter the patient's bladder wound. In addition, the annular folded end at the bottom end of the elastic hose has multiple annular folds extending outward. Even if the fistula tube moves up and down, the annular folds have a certain elasticity, which can still ensure the sealing of the space between the elastic hose and the fistula tube; therefore, frequent disinfection and dressing changes of the fistula opening can be avoided, reducing the nursing workload and the economic cost of treatment.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] See attached Figure 2 As shown, the present embodiment provides a maintenance-free sealing protective patch 100 for bladder fistula tube ostomy wound, which includes an elastic hose 1, a film 3 and a dressing extrusion layer 2. The film 3 is formed at the bottom end of the elastic hose 1 and is used to be adhered and fitted to the wound of the patient's bladder 300. The dressing extrusion layer 2 is arranged below the film 3 and is used to squeeze the dressing in the dressing extrusion layer 2 into the space between the elastic hose 1 and the fistula tube 200 after the film 3 is adhered and fixed to the skin of the patient's bladder 300.

[0022] Continue to refer to the attached Figure 2 As shown, the elastic hose 1 includes an elastic hose body 11 made of elastic material, the upper end of the elastic hose body 11 is formed with an open end 12 for inserting the fistula tube 200, the bottom end of the elastic hose body 11 is formed with a plurality of annular folded ends 13 extending outward in annular folds, and the open end 12 is connected to the annular folded ends 13. In order to improve the service life of the elastic hose 1, the annular folded ends 13 are integrally formed with the elastic hose body 11.

[0023] When in use, the fistula tube 200 can be inserted through the open end 12 on the elastic hose body 11 and extend downward from the annular fold end 13 to enter the wound of the patient's bladder 300. After the fistula tube 200 is inserted into the elastic hose 1, the open end 12 at the top of the elastic hose 1 fits on the outer surface of the fistula tube 200, and the upper end of the space formed between the outer surface of the fistula tube 200 and the inner wall of the elastic hose 1 is sealed to prevent external bacteria from entering the wound of the patient's bladder 300 through the space.

[0024] In order to improve the tightness of the upper end of the elastic hose 1 and the outer wall of the fistula tube 200, a blocking portion is formed on the inner wall of the opening end 12 at the upper end of the elastic hose body 11 to prevent the fistula tube 200 from falling off easily, and the fistula tube 200 is prevented from sliding easily by the extrusion contact between the blocking portion and the outer wall of the fistula tube 200. For example, the blocking portion can be formed on the inner wall of the opening end 12 with a plurality of annular valve protrusions extending toward the center, and the plurality of annular valve protrusions are arranged at intervals along the length direction of the elastic hose 1. When the fistula tube 200 is inserted into the inner cavity of the elastic hose body 11, the annular valve protrusion at the opening end 12 is in extrusion contact with the outer surface of the fistula tube 200, so that the fistula tube 200 will not easily slide out of the inner cavity of the elastic hose body 11.

[0025] Continue to refer to the attached Figure 2As shown, the film 3 extends from the opening of the annular fold end 13 at the bottom end of the elastic hose body 11 to the surrounding areas, and the dressing extrusion layer 2 is adhered to the bottom end of the film 3. In order to ensure the adhesion between the film 3 and the skin at the wound of the patient's bladder 300, the size range of the dressing extrusion layer 2 is smaller than the size of the film 3, and sufficient space is reserved on the periphery of the film 3 for adhering to the skin of the patient's bladder 300.

[0026] In some embodiments, the film 3 includes a waterproof and breathable film body and an adhesive layer arranged at the bottom end of the waterproof and breathable film body, for example, a 3M waterproof and breathable film structure is adopted.

[0027] In order to better understand the maintenance-free sealing protective patch 100 for cystostomy tube ostomy wound in this solution, the working principle thereof is briefly described below:

[0028] Combined with reference to Figure 3 To Attachment Figure 5 As shown, when installing or replacing a new fistula tube, it usually includes the following steps:

[0029] Step 1: After sufficient disinfection, clean the skin around the stoma;

[0030] Step 2: Pass the tip of the new fistula tube through the elastic hose 1;

[0031] Step 3: After the cystostomy tube is placed in the right position and fixed with a water bag;

[0032] Step 4: Push the sealing dressing toward the inner end of the body and stick it against the skin to complete the dressing change.

[0033] To remove the dressing, when replacing the cystostomy tube, suck out the liquid from the tube's water bag, remove the dressing together with the old cystostomy tube and discard it.
